Specification of Letters Patent.

Application filed October 5. 1905. Serial No. 281.544.

To aZZ whom, it may concern:

Be it known that I, RICHARD PFAFF, a subject of the German Emperor, residing at Zurich, Switzerland, have invented certain new and useful Improvements in Bottling- Machines, of which the following is a specification.

The present invention relates to bottling machines of the class described in the specification of previous Letters Patent granted to me No. 790455 dated 23rd May 1905, comprising means for holding on the bottles while being filled in which the pressure of the bottles against the fillin head is effected by the bottle holder and ottle thereon being adapted to be brought from an inclined position in which the bottle is adjusted into a vertical or almost vertical position in which the bottle is filled, said bottle holder being provided with a plate adapted to bear against the bottom of the bottle and being suspended in an oscillating manner above the cock spigot.

After the bottle is filled the bottle holder must be brought back into the inclined empty position for the purpose of removing said bottle and placing a new one in position and obviously considerable force is necessary for this purpose whereas on the oscillation of the bottle holder into the filling posi tion (said oscillation being caused by the weight of the bottle and bottle holder) a large part of this force is lost.

The object of the present invention is to store some of the force obtained on turning the bottle holder into the filling position so as to utilize it to assist that necessary for bringing the bottle holder back into the adjusting or empty position this being effected by means of tension springs, fixed at one end above the axis of rotation of the bottle holder and at the other end to the holder itself below its axis of rotation in such a manner that they will perform the triple function of holding the bottle holder in empty position until displaced, of holding it in filling position until displaced, and of bringing it from filling to empty position after an initial movement has been given to it for that purpose.

The invention is represented in the annexed drawing in which Figure l is a front elevation of a bottling machine of the class referred to provided. Figs. 2 and 3 are with this improvement.

side elevations partly in section of part of the machine on a larger scale, the latter figure showing also abottle in place in the filling position.

On the cock casing c, which is connected by means of the union 1) to the reservoir a, mounted on the frame A, is fixed the standard g carrying at its upper end a transverse bar 1). To a cross piece on said standard is pivoted the bow or frame 1 of the bottle holder 1, 2 said bow being provided below its pivotal axis with lateral hooks g. At the ends of the transverse bar p are hooks f, with which engage the helical tension springs 6 connected at their other ends to the aforesaid hooks g.

Near the point of connection'of the arms 2 to the bow l is ivoted one end of a rod 01 serving as a gui e and limit to the outward throw of the bottle holder, the other end of said rod passing through a slot 7c in a guide 8 mounted on a cross bar m of the frame A; a head or enlarged portion 9 prevents the rod *5 from being withdrawn from the slot lc.

The springs e fulfil three separate functions;

1st, they will hold the bottle holder in its forward or empty position. By a slight pressure, for'instance by hand, the bottle holder may be pushed back to the point of greatest tension of said springs, where the springs exercise no turning force on the bottle holder.

2nd, on passing this point the contraction of the springs 6 assists the movement of the bottle holder toward the abutment m and the tension of the springs e then acts to hold the bottle holder in the filling position independently of the pressure exerted through the bottle itself.

3rd. It only requires a slight pull to move the bottle holder with the filled bottle again beyond the points of greatest pressure on the bottle and greatest tension of the springs whereupon the contraction of the springs automatically efiects the further backward movement of the holder and bottle to the empty position limited by the guide rod i.

What I claim as my invention and desire to secure by Letters Patent of the United States 1s:

In a bottling machine of the character described the combination with a filling cock and a bottle pressing device comprising an oscillating bottle holder having its axis of robottle holder, said springs being so arranged tation above that of the cock spigot, of means position intermediate between the empty IO for facilitating the oscillation of the bottle and filling positions of the bottle holder subholder comprising tension springs connected stantially as and for the purpose described.
